| 2 | |
| 3 | The accelerator interface lets you drivers for external cryptoprocessors into an implementation of the [PSA Cryptography API](../#application-programming-interface). External cryptoprocessors such as secure elements and smart cards perform cryptographic operations with keys accessed via opaque handles. |
